摘　　要：本文研究了在50%NaOH,CH_2Cl_2体系中,苯骈15-冠-5催化产生的二溴卡宾与苯乙烯、多芳代苯乙烯反应的相对速率常数K_(rel),讨论了苯乙烯α及β位上芳基取代基数目和空间位置对K_(rel)的影响.Styrene and aryls substituted styrenes were prepared, and the relative rate constants (K_(rel)) of cycloaddition reaction of these substituted styrenes with dibromocarbene were measured under phase transfer catalysis condition.
